A remarkable species really of the Dasycladum Series but 
simulating in vegetative form and grosser flower characters Rh. 
gloeoblastum, Balf. f. et Forrest of the Souliei Series. It is 
readily distinguished amongst its allies of which perhaps Rh. 
iruncatulum, Balf. f. et Forrest is the nearest by the marked thin 
indumental! veil of yellow branched sebaceous hairs covering the 
underleaf surface.
